Abstract (en)
[origin: US4561056A] In an electronic control apparatus for an internal combustion engine, the contents of a selected reference register are compared with the count contents of a timer so that when equality is found therebetween, an interrupt signal is applied to a central processing unit, which then computes when and how a control condition is to be changed with respect to one of a plurality of controlled systems and the contents of the reference register are updated accordingly. In addition, a plurality of actuators for controlling the operation of the engine are selectively controlled in accordance with control signals generated from the central processing unit on the basis of the receipt of the interrupt signals.
